The technical solution adopted for the present invention to solve the technical problems is: construct the adjustable light fixture of a kind of light angle, comprise support and lamp holder, it is characterized in that, the worm screw in the output shaft dead ahead that also comprise the motor that is fixed on the described support, is positioned at described motor, with described worm screw one end be connected motor output shaft connect make the two shaft coupling that rotates synchronously, with the worm gear of described worm engaging and the rotating shaft that is arranged with described worm gear and rotates synchronously with it; Described rotating shaft is fixedly connected with described lamp holder, and described rotating shaft is fixed on the support.
In the adjustable light fixture of light angle of the present invention, the centre of described rotating shaft is installed with described lamp holder, and two ends are installed on the two ends of described support.
In the adjustable light fixture of light angle of the present invention, described worm gear set is located at an end of described rotating shaft, and with described worm engaging, but described worm and gear self-locking.
In the adjustable light fixture of light angle of the present invention, described worm screw two ends are respectively installed with bearing, and described bearing all is contained on the support.
In the adjustable light fixture of light angle of the present invention, described worm screw one end stretches out described bearing and is connected with shaft coupling one end, and the described shaft coupling other end is connected with the output shaft of described motor.
In the adjustable light fixture of light angle of the present invention, also comprise the receiver module of the wireless signal that receives the described motor operating state of control, the processing module that described wireless signal is processed and the driver module that drives described motor according to the output of described processing module.
In the adjustable light fixture of light angle of the present invention, described wireless signal is sent by transmitter module.
In the adjustable light fixture of light angle of the present invention, described receiver module, processing module and driver module all are integrated in the control casket.
Implement the adjustable light fixture of light angle of the present invention, have following beneficial effect: the present invention realizes the moment of motor is passed to lamp holder by drive structure of gear worm, make the light angle of lamp holder adjustable, can enlarge illumination zone or adjust light angle according to lighting demand; But the worm and gear self-locking of simultaneously this device employing also can normally be used the not charged lamp holder that makes of motor, avoids occurring the problem of the uncontrolled random rotation of lamp holder; In addition, the present invention adopts standard component mostly, and cost is low, and reliability is high, but has generalization.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the fitting structure schematic diagram of prior art;
Fig. 2 is the structural representation of the preferred embodiment of the adjustable light fixture of light angle of the present invention;
Fig. 3 is the left view of preferred embodiment shown in Figure 2.
The specific embodiment
In the preferred embodiment shown in Fig. 2, the light fixture that light angle of the present invention is adjustable comprises the parts such as lamp holder 10, rotating shaft 20, worm gear 30, worm screw 40, shaft coupling 50, motor 60 and support 70.
By Fig. 2, Fig. 3 as can be known, support 70 is " Contraband " shape, and the two ends of rotating shaft 20 respectively are enclosed within on the bearing, and each bearing namely is contained in the corresponding hole of offering, two ends of support 70, guarantees that rotating shaft 20 is free to rotate on support 70.Lamp holder 10 is fixed on the centre of rotating shaft 20, and rotating shaft 20 can drive lamp holder 10 and rotate.
Each cover of the two ends of worm screw 40 has 41, two bearings 41 of a bearing to be contained in respectively in the hole that two of support 70 pick up the ears to offer on 71.The end of worm screw 40 reaches the outside of corresponding bearing 41 and is connected with an end of shaft coupling 50, and the other end of shaft coupling 50 is connected with the output shaft of motor 60 output rotating torques.Shaft coupling 50 also has buffering and offsets motor 60 and the effect of worm screw 40 in the error of installing except connecting worm 40 and motor 60.
As known from the above, motor 60 rotations will drive worm screw 40 and rotate synchronously, and worm screw 40 drives worm screws 30, and worm gear 30 drives rotating shafts 20, and rotating shaft 20 drives lamp holders 10 and rotates.As described in Fig. 2, Fig. 3, motor 60 is installed on the support 70.Therefore, only need the states such as the ON/OFF of control motor 60 and the speed of service, can regulate irradiating angle and the irradiation distance of lamp holder, satisfy under various illuminations place and the lighting condition demand to angle.Because worm screw 30, worm screw 40 have auto-lock function, when motor does not turn round, the self-locking of worm gear 30 worm screws 40 so that lamp holder 10 can not rotate yet, simultaneously worm and gear engagement better drive moment is large, even lamp holder 10 is heavier, worm and gear still can drive freely lamp holder 10 rotations and adjust angle, reliable in structure of the present invention.
In order to strengthen the effect of automatic adjusting light angle of the present invention, the light fixture that the light angle of this preferred embodiment is adjustable also comprises an operation casket, and the integrated a plurality of modules that realize distant control function can realize the remote control adjustment to lamp holder 10 angles in the operation casket.Described integrated a plurality of modules comprise receiver module, processing module and driver module.Operating personnel hold transmitter module, and described transmitter module is generally the remote control equipments such as remote controller, can launch wireless signal.
Receiver module receives the wireless signal from transmitter module, and these wireless signals are used for the running status of control motor 60, comprise ON/OFF, rotating speed, the duration of runs etc.Processing module can be processed the wireless signal that receives, and output data/signal.Driver module comes drive motors 60 according to the output of processing module, implements the corresponding motor operating state of wireless signal.Therefore, operating personnel only need control by the mode of remote control the rotation of motor 60, can realize the Long-distance Control of lamp holder 10 irradiating angles and irradiation distance.
The above is described embodiments of the invention by reference to the accompanying drawings; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
